CLAYTON — A telephoned bomb threat, including a declaration that hostages were being held and a demand for an armored car and $15,000 in cash, shut down Route 47 here from about 5:30 p.m. Monday to 1:19 a.m. Tuesday.

The caller, whose voice reportedly sounded distorted, according to police, said he’d put bombs in the neighborhood around a house on East Center Street and that he had taken hostages.

The Camden County Sheriff’s Department Technical Services Unit — the bomb squad — and the Gloucester County Special Weapons and Tactics team were called out.

Automated telephone messages went out to some residents, advising them to remain inside, police said. Fourteen houses reportedly were evacuated.

Bomb sniffing dogs did sweeps of the police station and surrounding buildings and police had airspace over the East Center Street house — which had been vacant for several months — restricted during the incident.

Before discovering the furnished house was vacant, members of the SWAT team used a public address system mounted in an armored vehicle to try to communicate with anyone who was inside.

A bomb squad robot was used to clear some first-floor rooms in the two-story Cape Cod-style house at about 10:38 p.m. and the whole house was cleared by members of the SWAT team, bomb technicians and K9 units at about 11:28 p.m., according to police.

After the house was cleared and nothing was found, K9 units did one more search in the neighborhood.

Roads were opened at 12:10 a.m. and the airspace restriction was lifted at 12:26 a.m. An all-clear notice was telephoned to residents at 1:18 a.m.
